Ultimate TV technology meets sensationally sleek and compact design, with LG’s flagship 48 inch TV – the LG OLED48G66LS.
Compact size, class-leading performance
Perfect for when you want a premium TV in a smaller space, the LG OLED48G66LS delivers flagship performance from a 48 inch TV. Thanks to the latest TV tech, it’s also at the top of its game in performance terms. LG’s ultimate panel, with Hyper Radiant Colour Technology, including Brightness Booster Ultra delivers sensational pictures. Combined with powerful, AI-enhanced processing, the picture maintains supreme brightness and image clarity, even in brighter rooms. With its ultra-slim Gallery design you also get iconic aesthetics. Super-responsive gaming and the best in Smarts completes this talented TV.
Next level picture – Hyper Radiant Colour Technology
Taking LG’s premium Primary RGB Tandem 2.0 panel as its basis, this LG 48 inch TV delivers truly stunning brightness and picture contrast. Featuring Brightness Booster Ultra, this intensely bright panel is an incredible 3.9 times brighter than the B6 model and an impressive 20% brighter than last year’s G5 model. The result is incredible colour realism and depth – even in brighter rooms.
Anti-reflection screen technology for a clearer image
Working in conjunction with the Hyper Radiant Colour Technology, the LG OLED48G66LS features an anti-reflection screen surface. Earning the industry-first Reflection Free Premium certification from Intertek, the screen now displays the Perfect Blacks and Perfect Colours that the best OLED screens are renowned for, even in brightly lit rooms.
Picture perfection, with Alpha 11 AI Processor Gen 3
Fitted with LG’s premium Alpha 11 AI Processor Gen 3, the picture quality is sharper, more natural and supremely balanced for the best in clarity and picture precision. Featuring Dual Super Upscaling it can simultaneously process two types of AI upscaling. With its 50% faster CPU (Central Processing Unit) and 70% faster GPU (Graphics Processing Unit), the immensely powerful ‘brains’ behind this TV deliver outstanding picture immersion.
Sleek, Gallery style, with stand included
Supplied with a desktop stand, this super-slimline TV takes pride of place in your room, without dominating it. The G-Series uses LG’s ‘4 Side Cinema’ screen for a clean, near-bezel-less image. When switched off, you can display digital images and photos for a gallery effect.
A master with movies
Fitted with a native 120Hz display, bright screen and host of HDR enhancements, including Dolby Vision, this LG 48 inch OLED TV delivers cinematic smoothness and colour depth. For the very best experience, Filmmaker Mode with Ambient Light Compensation lets you enjoy cinematic vision in all lighting conditions, exactly as the director intended, right down to using the correct aspect ratio, colour and frame rate.
Geared up for gaming
With its wide range of gaming enhancements, LG once again remains the first choice for many gamers. With a response time of less than 0.1ms, it’s super-fast to react to your every move. LG’s Game Optimiser gets you quick access to important settings. This model now supports 4K 120Hz game streaming from NVDIA’s GeForce Now. HDMI 2.1 connections ensure support for 4K 165Hz gaming from PCs and 4K 120Hz gaming consoles. Certified by Dolby Vision for Gaming, NVIDA G-SYNC and AMD FreeSync Premium, you can enjoy tear-free and stutter-free gaming, with minimal lag.
Smooth and spacious sound
Featuring a 2.2 channel speaker array with Dolby Atmos compatibility and AI Object remastering Ultra, this stylish TV delivers a clear, richly-balanced sound. AI Sound Pro up-mixes two-channel audio to virtual 11.1.2 sound – producing a more immersive sound and enhanced dialogue. Pair with an LG soundbar and the sophisticated WOW Orchestra processing splits the sound output between TV and soundbar, for a smoother, more enveloping sound.
LG webOS 26 for faster and smoother Smart TV
Featuring multi-AI architecture, LG’s webOS 26 Smart TV operating system is better than ever. Deeper AI integration ensures faster and more intuitive searching, with Microsoft Copilot on hand to ask about TV content and more. In addition, Google’s Gemini (available via optional subscription) provides a second tier of AI-enhancement with extra features, such as the inclusion of AI generated artwork and images to the LG Gallery+ section. For continued innovation, LG offer five years of free OS updates, meaning that today’s LG TVs will be just as Smart savvy in years to come.*
*Future OS updates may not contain all features, due to potential TV hardware constraints.
AI makes operation easier than ever
Power up your new TV and a raft of AI technologies make it easier to find just what you’re looking for. Featuring AI Agent, Intelligent Voice Recognition and AI Concierge, you’re offered recommendations that are unique to your viewing habits. For simple interaction with your TV, there’s even an AI Chatbot that can proactively search for solutions to operational challenges you might have.
